specific Embodiment approach 1

[0030] Specific implementation mode one: see figure 1 Describe this embodiment, the safety detection and early warning device for the running part of the railway vehicle described in this embodiment, it includes a wheel signal acquisition and distribution module 1, a car number acquisition module 2, a sound acquisition and processing module 3, a temperature acquisition and processing module 4, an image acquisition module and processing module 5, power acquisition and processing module 6, laser image acquisition and processing module 7, host computer 8, display 9 and alarm device 10;

[0031] The wheel signal collection and distribution module 1 is used to collect the wheel passing signal. When the wheel passing signal is collected, the vehicle number collection module 2, the sound collection and processing module 3, the temperature collection and processing module 4, the image collection and processing module 5, The power acquisition and processing module 6 and the laser image...

specific Embodiment approach 2

[0052] Specific implementation mode two: see figure 1 Describe this embodiment, the difference between this embodiment and the railway vehicle running part safety detection and early warning device described in the first embodiment is that the sound collection and processing module 3 is used to collect the sound of the bearing passing the vehicle, and to analyze the sound of the bearing The specific process of diagnosis is as follows:

[0053] Match the collected bearing sound of the passing vehicle with the sound of the faulty bearing in the database of the sound collection and processing module 3. When the matching is successful, it is determined that the bearing of the passing vehicle has a fault defect. When the matching fails, it is determined that the bearing of the passing vehicle is running. Normal, and extract the sound information of the faulty bearing;

[0054] The bearing sound in the database is the sound when the bearing is faulty.

[0055] In this embodiment, ...

Abstract

The invention relates to a safety detection forewarning device of running parts of a railway vehicle, and belongs to the technical field of safety detection of railway vehicles. The safety detection forewarning device solves the problem that manual detection for vehicles on railway is low in efficiency. The safety detection forewarning device comprises a vehicle wheel signal acquiring and distributing module, a vehicle number acquiring module, a sound acquiring and processing module, a temperature acquiring and processing module, an image acquiring and processing module, a power acquiring andprocessing module, a laser image acquiring and processing module, a main computer, a displayer and an alarm device. When the vehicle running on a railway line passes through the safety detection forewarning device, the safety detection forewarning device detects the vehicle in the following steps of: detecting the running part of the vehicle; enabling all acquisition modules to analyze and processthe acquired data to determine whether the working state of the parts of the detected vehicle is normal; and finally, combining analysis data from the modules to perform fault content forecasting. The safety detection forewarning device disclosed by the invention is mainly used for detecting vehicles passing through the device.

Description

technical field [0001] The invention belongs to the technical field of railway vehicle safety detection. Background technique [0002] Railway is an important mode of transportation in my country, providing an important logistical guarantee for the rapid and stable development of the economy, and the safety of vehicles running on railway lines is the focus of attention of the railway department. Only through manual detection, the detection efficiency is low, and in a special working environment (for example: narrow working space), manual detection is difficult, time-consuming and labor-intensive, and the detection efficiency is low. In order to realize the monitoring and early warning of railway vehicles, the Railway General The company has invested a lot of manpower and material resources. Under this background, it is very necessary to invent a device for safety detection and early warning of the running part of the railway vehicle. Contents of the invention [0003] The...
